n8n vs Sim
Is it time to switch? We break down the differences so you can stop bleeding money.
Choose n8n.
If you want to own your data, save money, and avoid vendor lock-in, n8n is more popular among developers.
What Actually Matters
No fluff — just the differences that affect your decision
Both open source, different licenses: n8n uses Sustainable Use License, Sim uses Apache-2.0. Check the fine print if you're building commercial.
n8n lets you self-host with Docker — your data, your rules. Sim? Cloud only. If privacy matters, that's a dealbreaker.
n8n dominates with 207.3k GitHub stars vs 29.8k. Bigger community = more plugins, more answers on Stack Overflow, faster bug fixes.
Both written in TypeScript. Same ecosystem, same talent pool — makes switching easier if you ever need to.
Try both — most offer free tiers. The right pick depends on your stack size, team, and tolerance for DevOps.
